TRACTOR WINCH.

.Application filed August 29, 1927. Serial No. 216,130.

This invention relates to a form of power winch which is adapted to bemounted on a tractor of any desired type, and to be driven by power fromthe tractor engine under con- 6 trol of the operator. It isy the purposeof the invention to provide a very simple and eiiicient mechanism ofthis character, which is normally held by a brakel against accidentaloperation, but in which the brake may be released by a slight movementof an operating ,lever While a further movement othe lever in the samedirection will connect the winding drum of the power winch with amachinedriven part for the purpose of operating the winch. When pressureon the lever is released, it will be returned by spring to its originalposition. Details of theinvention will be apparent from the followingdescription and the appended claims.

In the drawings:

Figure 1 is a rear elevation of the invention mounted on a tractor.

Figure 2 is a side elevation with the parts in normal position.

the parts in operative position.

Figure 4 is a side view and Figure 5 is an end view of a supporting andoperating member.

The invention may be applied to any desired form of tractor, and, asillustrated,

there isshown a rear portion of a conventional machine having a body A,rear axle B, rear wheels C, a housing D for said rear wheels, and otherparts of the mechanism, and a draw bar E. All of these parts may be ofany old or desired construction.

A supporting framework 1 extends beyond the housing for the rear wheels,and this frame carries a supporting device comprising vertical brackets2 and a horizontal base member 3. Rising from the base member 3 arebrackets 4, in which is mounted a shaft 5 carrying a pivotal gear Gwhich meshes with a pivotal gear 7 on a shaft driven by the engine ofthe tractor in any desired manner. One end of the shaft 5 carries alibre or similar friction wheel 8.

A Ushaped member 9, shown particularly in Figures 4v and 5, has bearings10 by means of which it is mounted on one end of a shaft 11, which ismounted in the upright 2. This shaft carries a winding drum 12 and agear 13 on the other end, but the power may be Figure 3 is a similarside elevation with transmitted to other devices when desired.

`adapted to be brought into frictional engagementwith the libre wheel 8as hereinafter set forth.

A rod 19 is attached to a fixed' portion of the framing as at 20, andpivoted thereon at'21 is a hand lever 22. The lower end of this lever ispivoted at 23 to the lower portion of the U-shaped member 9. Thedistance between the pivots 21 and 23 is quite short compared with thedistance between the pivot 21 and the operating ends ofthe lever 22. Abolt or similar member' 24 is also fastened to the framing at v25, andpasses through an opening 26 in the lower part of the U-shaped member`9. A spring 27 surrounds the bolt 24 on the other side of the member 9and is held in position by a nut on the lower end of this bolt.

A brake member 28 is fastened to the lever 22 at 29, vand also has anend 30 engaging about a pivot at the point 23. The pivot 29 is locatedmuch further from the pivot points 21 of the lever 22 than is the pivot23, so that a movement of the lever 22 will release the brake beforeproducing any substantial movement of the U-shaped member 9 and thegearing carried thereby.

The operation of the device may be briefly described as follows. Whenthe parts are in the position shown in Figure 2, the brake member 28 isin engagement with the friction wheel 18, and all of the parts are heldagainst accidental movement.v If it is desired merely to release thebrake, the lever is given a slight movement in the direction of thearrow in Figure 3, which will release the brake, but will not bring thefriction wheel 18 into contact with the Wheel 8. If it is desired towind up on the drum 12 a cable F which passes around a pulley G to anydesired point, the lever 22 will be moved still further in the directionindicated in Figure 3, thus swinging the member 9 and the gears carriedthereby until the friction Wheel 18 engages the wheel 8 and is driven`by the same. This movement will be transmitted through the shaft 15,gears 16 and 17, and shaft 11 to the winding drum l2, and the cable willbe wound thereon.

When it is desired to cease the movement, it is necessary only torelease the lever 22, whereupon the spring 27Will return the parts tothe Figure 2 position, placing the friction wheel 18 out of Contact withthe wheel 8, and applying the brake member 28 with sufficient force tohold the parts against accidental movement.

It will be obvious that the invention provides a 'very compact andsimple arrangement for obtaining the desired result, and all of themechanism may be enclosed by a cover if desired, since it is necessaryonly to provide a short slot to permit movement of the lever 22 and anopening for the passage 0f the cable F. The construction may be modifiedto adapt the same for various types of tractors, and various details maybe changed Without departing 'from the spirit of the invention, which isto be regarded as limited only by the scope of the appended claims.

We claim as our invention:

1. A tractor winch comprising a friction wheel driven from a suitablesource of power, a Winding drum, a shaft therefor, a gear Wheel on saidshaft, a frame mounted to swing on said shaft, a second gear Wheelmeshing with the rst and carried on a stub shaft'mounted in said frame,a second fric-- tion wheel on said stub shaft, a brake normally engagingthe second friction wheel, and a lever connected to said brake and saidframe so that the movement of the lever releases the brake and bringsthe two friction wheels into engagement to drive the winding 4 drum.

2. A tractor winch comprising a friction Wheel driven lfrom a suitablesource of power, a winding drum, a shaft therefor, a gear wheel on saidshaft, a frame mounted to 4 swing on said shaft, a second gear wheelmeshing with the first and carried on a stub shaft mounted in saidframe, a second friction Wheel on said stub shaft, a brake normallyengaging the second friction wheel, 5 a lever connected tosaid brake andsaid frame so that the movement of the lever releases the brake andbrings the two friction Wheels vinto engagement to drive the Windingdrum, and spring means for returning 5 the lever to normal position whenreleased.

3. A tractor winch comprising a friction Wheel driven from a suitablesource of pow er, a winding drum, a shaft therefor, a gear Wheel on saidshaft, a U-shaped f rame mounted to swing on said shaft, a second gearwheel meshing with the first and carried on a stub shaft mounted in saidU- shaped frame, a second friction Wheel mounted on said stub shaft, abrake nor- 6 mally engaging the second friction Wheel, a lever connectedto said brake and lto said U-shaped' frame, and means for mounting saidlever so that a slight movement Will release the brake while a furthermovement is necessary to bring the two friction -wheels into engagementto drive the Winding drum.

n testimony whereof we affix our signatures.
